Abstract
Description
- The present invention generally relates to a wireless communication system, and more particularly to a method and system for allocating uplink and downlink data bursts in a wireless communication system.
- Extensive research is being conducted on fourth-generation (4G) communication systems serving as next generation communication systems that provide users with services based on various qualities of service (QoS) at a transmission rate of about 100 Mbps. In the current 4G communication system, extensive research is being conducted to ensure mobility and QoS and support high-speed services for broadband wireless access (BWA) communication systems such as a wireless local area network (LAN) system and a wireless metropolitan area network (MAN) system. A typical communication system is based on the Institute of Electrical and Electronics Engineers (IEEE) 802.16 communication system standard.
- The IEEE 802.16 communication system is a BWA communication system using orthogonal frequency division multiplexing/orthogonal frequency division multiple access (OFDM/OFDMA). As compared with the conventional wireless technology for a voice service, the IEEE 802.16 communication system can transmit a large amount of data in a short time using a wide data bandwidth and can efficiently use a channel because the users can share a common channel. In the IEEE 802.16 communication system, all users associated with a base station (BS) share a common channel. Since the BS allocates an interval in which each user uses a channel for each uplink (UL) or downlink (DL) frame, the BS notifies the mobile stations of UL and DL access information so that the users can share the common channel. UL and DL MAP messages are used to supply the notification of the UL and DL access information.
- A hybrid automatic repeat request (H-ARQ) MAP message is a type of MAP message used to support a mobile station (MS) available in an H-ARQ scheme. For example, the MS interprets an H-ARQ MAP message when receiving the message from the BS. A MAP information element (IE) included in the H-ARQ MAP message is referred to as a compact UL/DL MAP IE. The MS can receive or transmit a data burst according to information of Compact UL/DL-MAP_IE.
- FIG 1 illustrates a frame structure used in a conventional wireless communication system.
- Referring to FIG. 1, a frame can be divided into a DL subframe and a UL subframe.
- The DL subframe includes a
preamble transmission interval 10, aMAP transmission interval 20 and adata transmission interval 30. - The
MAP transmission interval 20 includes a frame control header (FCH) 21 for transmitting information for decoding and demodulating MAP information and H-ARQ MAP 1 22 and H-ARQ MAP2 23 for transmitting information to a desired MS. Thedata transmission interval 30 includes allocated data bursts to be transmitted to the MS using a plurality of subchannels in a specific symbol interval. Here, the data bursts are sequentially allocated in a subchannel unit of a vertical axis during a unit symbol interval of a horizontal axis. When data burst allocation is completed for all subchannels of one symbol interval, data bursts are sequentially allocated in the subchannel unit during the next symbol interval. - That is,
Data Bursts Data Burst 1, the BS allocatesData Burst 2 toSubchannels 6 to 8 and then allocatesData Burst 3 toSubchannels 9 to 10. - When the data burst allocation is completed in the 'n' symbol interval, the BS sequentially allocates
Data Bursts - Next, the UL subframe will be described. The UL subframe includes a control
information transmission interval 40 and adata transmission interval 50. - Data bursts for UL signal transmissions of MSs are allocated in one dimension in the
data transmission interval 50 of the UL subframe as in thedata transmission interval 30 of the DL subframe. That is, the end time of a previous data burst corresponds to the start time of the next allocated data burst. - When the BS (or higher-level stage) allocates data bursts in one dimension as described above, MAP overhead can be minimized. However, it is difficult for a specific data burst to be applied to a modulation and coding scheme. In other words, the modulation and coding scheme is applied in a symbol interval unit. The modulation and coding scheme cannot be applied when a specific data burst is allocated during two symbol intervals.
- When the BS and a neighbor BS operate in an identical subchannel band, interference between the BSs results in data burst loss. Accordingly, data transmission efficiency is degraded.
- It is, therefore, an object of the present invention to provide a method and system for efficiently allocating data bursts in a wireless communication system.
- In accordance with an aspect of the present invention, there is provided a method for allocating data bursts in a wireless communication system, the wireless communication system having a frame set by a symbol interval axis and a frequency band axis, the frame including a first region in which a MAP message is transmitted and a second region to which the data bursts are allocated, the method including the steps of setting a third region based on a symbol interval and a frequency band in the second region, and sequentially allocating the data bursts to the third region from a first symbol interval along the frequency band axis.
- In accordance with another aspect of the present invention, there is provided a system for allocating data bursts in a wireless communication system having a frame set by a symbol interval axis and a frequency band axis, the frame including a first region in which a MAP message is transmitted and a second region to which the data bursts are allocated, the system including a base station for setting a third region based on a symbol interval and a frequency band in the second region, and sequentially allocating the data bursts to the third region from a first symbol interval along the frequency band axis.
- The above and other objects and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
- FIG. 1 illustrates a frame structure used in a conventional wireless communication system; and
- FIG. 2 illustrates a frame structure used in a wireless communication system in accordance with an embodiment of the present invention.
- Preferred embodiments of the present invention will be described in detail herein below with reference to the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings.
- In the following description made in conjunction with preferred embodiments of the present invention, a variety of specific elements such as concrete messages and signals are shown. The description of such elements has been made only for a better understanding of the present invention. Those skilled in the art will appreciate that the present invention can be implemented without using the above-mentioned specific elements. In the following description, detailed descriptions of functions and configurations incorporated herein that are well known to those skilled in the art are omitted for the sake of clarity and conciseness.
- The present invention proposes a method and system for setting a two-dimensional region to allocate uplink (UL) and downlink (DL) data bursts in a frame of a wireless communication system and allocating the data bursts of the set region in a single dimension. For example, a hybrid automatic repeat request (H-ARQ) MAP message will be described. The present invention can also use MAP messages such as DL-MAP and UL-MAP messages defmed in the Institute of Electrical and Electronics Engineers (IEEE) 802.16 standard.
- FIG. 2 illustrates a frame structure used in a wireless communication system in accordance with an embodiment of the present invention.
- Referring to FIG. 2, a frame is configured by a DL subframe and a UL subframe. The DL subframe includes a
preamble transmission interval 210, aMAP transmission interval 220 and adata transmission interval 230. - The UL subframe includes a control
information transmission interval 240 and adata transmission interval 250. - Since the DL and UL subframes of FIG. 2 have structures similar to those of FIG 1, a concrete description of the DL and UL subframes of FIG. 2 is omitted. In the frame, the horizontal axis represents symbol intervals and the vertical axis represents subframes. It is noted that data burst allocations in the
data transmission interval 230 of the DL subframe and thedata transmission interval 250 of the UL subframe in accordance with the present invention are different from the conventional one-dimensional data burst allocation. Specifically, a base station (BS) uses the conventional one-dimensional data burst allocation method for sequentially filling subchannels during one symbol interval and sequentially filling other subchannels during the next symbol interval. The present invention can use not only a data burst allocation method in one dimension, but also a new data burst allocation method in two dimensions. - The following is a description of a data burst allocation method based on the two-dimensional form.
- Data Bursts 1, 2, 3, 4 and 5 are allocated to the
data transmission interval 230 of the DL subframe of FIG. 2 as in the conventional one-dimensional burst allocation. Aregion 260 of Data Bursts 6, 7, 8 and 9 as indicated by the bold lines in thedata transmission interval 230 of the DL subframe is allocated in the two-dimensional form. Similarly, aregion 270 of Data Bursts 3, 4, 5 and 6 as indicated by the bold lines in thedata transmission interval 250 of the UL subframe is allocated in the two-dimensional form. - The BS designates a start point using a symbol offset and a subchannel offset to designate the two-dimensional data burst
regions regions regions - For example, it can be found that Data Bursts 6, 7, 8 and 9 of the
data transmission interval 230 occupy two symbol intervals, which are assumed as 'n' and 'n+1', subchannels of the 'n' symbol interval are partially used and some subchannels are used in the next `n+1' symbol interval from FIG 2. If the data bursts are allocated in the one-dimensional form, Data Bursts 6 and 7 must be allocated to some subchannels of the 'n' symbol interval and Data Bursts 8 and 9 must be allocated to the remaining subchannels of the 'n' symbol interval. - A method for configuring MAP information for the two-dimensional data burst allocation in accordance with an embodiment of the present invention will be described.
- Table 1 shows the format of a 'Compact DL-MAP IE' message used during a one-dimensional data burst allocation, Table 2 shows the format of a 'Compact DL-MAP IE' message used during a two-dimensional data burst allocation and Table 3 shows the format of a 'Compact UL-MAP IE' message used during a two-dimensional data burst allocation.

- In the 'Compact_DL-MAP_IE' message for the one-dimensional data burst allocation as shown in Table 1, a combination of values of the 'NEP code' and 'NSCH code' fields can indicate the number of allocated subchannels and a scheme of coding and modulation. The BS starts the data burst allocation from a first subchannel of a first symbol interval and allocates a first data burst corresponding to the number of subchannels set by the combination of the values of the 'NEP code' and 'NSCH code' fields. The allocation end point of the first data burst becomes the allocation start point of the next second data burst. The one-dimensional data burst allocation method can reduce the overhead in a region of H-
ARQ MAPs - Table 2 shows the 'Compact DL-MAP_IE' message for two-dimensional data burst allocation in accordance with an embodiment of the present invention. The 3-bit 'DL-MAP Type' field indicates a type of DL-MAP. The 5-bit 'DL-MAP sub-type' field indicates a sub-type of DL-MAP. The 4-bit 'Length' field indicates a length of an IE. The 7-bit 'OFDMA Symbol offset' field indicates a symbol start position of an allocated two-dimensional region. The 6-bit 'Subchannel offset' field indicates a subchannel start position of an allocated two-dimensional region. The 6-bit 'No. OFDMA Symbols' field indicates the number of symbols allocated to the two-dimensional region. The 6-bit 'No. Subchannels' field indicates the number of subchannels allocated to the two-dimensional region. The 3-bit 'Boosting' field indicates whether subcarrier power has been amplified. The variable-length 'Compact DL-MAP_IE for Diversity' field is used to allocate data bursts to the two-dimensional region in one dimension. The 'Compact DL-MAP_IE for Diversity' field includes all the fields as shown in Table 1.
- The fields used to designate a region for allocating two-dimensional bursts are the 'OFDMA Symbol offset', 'Subchannel offset', 'No. OFDMA Symbols', and 'No. Subchannels' fields. That is, a value of the 'OFDMA Symbol offset' field indicates a point of a symbol interval from which the data burst allocation starts in the
data transmission interval 230 of FIG. 2. A value of the 'Subchannel offset' field indicates a subchannel point from which the data burst allocation starts in thedata transmission interval 230. As described above, the BS designates the start point of a two-dimensional data burst allocation region using the 'OFDMA Symbol offset' and 'Subchannel offset' fields. When the number of symbols and the number of subchannels are set according to the values of the 'No. OFDMA Symbols' and 'No. Subchannels' fields, a total two-dimensional data burst allocation region is completely set. - The BS allocates data bursts to the completely set two-dimensional data burst allocation region according to the one-dimensional data burst allocation method.
- The method for setting a two-dimensional data burst allocation region in a DL subframe and allocating data bursts to the set region in one dimension can be equally applied to the allocation method in a UL subframe.
- Table 3 shows the format of the Compact_UL-MAP_IE message. Since the fields of the Compact_UL-MAP_IE message of Table 3 are very similar to those of the Compact_DL-MAP_IE message of Table 2, a description thereof is omitted.
Table 3 Syntax Size Notes Compact_UL-MAP_IE for Zone based allocation { UL-MAP Type =7 3 bits UL-MAP sub-type = 4 5 bits Zone based H- ARQ Configuration Length 4 bits OFDMA Symbol offset 7 bits Offset from the start symbol of UL subframe Subchannel offset 6 bits No. OFDMA Symbols 6 bits No. Subchannels 6 bits for (i=0;I<#of IE;i++ Compact_DL-MAP_IE for Diversity variable } padding bits variable shall be set to 0 } - As is apparent from the above description, the present invention can improve the data transmission efficiency by setting a specific region in two dimensions and allocating uplink (UL) and downlink (DL) data bursts to the set region in one dimension in a wireless communication system.
